INTRODUCTION — —————
Your new GXC-760D Cassette Tape Deck is made
of the very finest materials and incorporates the
very latest in recording and playback techniques.
In addition to the features outlined in this manual,
AKAI's superior A.D.R (automatic distortion reduc-
tion) System which changes the recording equalizer
characteristics according to the signal level of a
certain frequency band to achieve low distortion
over an extended frequency range is also incorpo-
rated in this model. This together with many other
outstanding features including a 3-motor, 3-head
system and AKAI’s wear-free GX-Heads combine to
bring you the finest in cassette recording and play-
back. We, therefore, urge you to READ THIS
MANUAL THOROUGHLY BEFORE ATTEMPTING
OPERATION.
CASSETTE TRACK SYSTEM
É HEAD
SIDE B TRACK 4 |(L)
SIDE B TRACK 3 |(R)
SIDE A os TRACK 2 |(R)
SIDE A [tee | TRACK 1 |(L)
This model employs a 4-track recording/playback
system. The first half of the stereophonic recording
or playback take places on tracks 1 and 2. The second
half takes places on tracks 3 and 4 after the cassette
has been inverted. Recording and playback depends
upon the length of the tape (C-30, 30 minutes;
C-60, 60 minutes, etc.). Monaural and stereo record-
ed tapes can be played back on either stereo or
monaural cassette recorders without any loss in
quality. Because the total track width of the left
and right channels is equal to that of the monaural
track, the playback head will scan both left and
right channels together. This results in automatic
mixing of left and right channels from the stereo
tape for monaural reproduction.
TAPE SELECTION
This machine is equipped with Tape Selector
Switches which set the machine to proper bias and
equalization according to the tape being used. De-
press the LOW NOISE Switch when using low
noise tape, and depress the CHROME Switch when
using chromium dioxide tape. Depress both switches
simultaneously when using Ferri-Chrome tape.
* Low noise tape is standard for this machine.
The use of ordinary tape will result in inferior
performance.
DIRECT FUNCTION CHANGE CONTROL————
This model features feather-touch Full Direct Func-
tion Change Control. The necessity of depressing
the Stop ll Button prior to changing modes is elimi-
nated. The inclusion of direct function change to
recording mode facilitates easy add-on recording.
AUTOMATIC STOP
This machine employs full release automatic stop
wherein at the end of the tape, the head block
completely separates from the tape and capstan.
Protects tape and prevents pinch wheel wear.
PEAK CHECK
The GXC-760D is equipped with a Peak Check
Switch. When this switch is depressed, the VU Meters
are set to —8 dB (marked with red marker on VU
Meters) in relation to a continuous O VU sinewave
signal.
Therefore, adjustment of the peaking level of re-
cording input signals can be accomplished as follows:
1. Adjust Recording Level Controls and set to
position at which the normal recording level is
"0" VU.
2. Depress the Peak Check Switch and re-adjust so
that only the heaviest peak parts reach, but de-
finitely do not exceed, “0” on the VU Meter
scales.
* This feature is especially convenient for fine
adjustment of pulsive input signal peaks (such as
when recording from percussion instruments, etc.)
so that the full dynamic range of the tape can
be utilized without incurring distortion caused
by over-recording.
SOUND MONITORING
For precise recording level adjustment, set Monitor
Switch to SOURCE position and monitor signals
through headphones while adjusting input level
controls.
Dual monitoring can also be accomplished with this
.machine by switching the Monitor Switch to and
from TAPE and SOURCE to compare the signals
being recorded with the input source. Separate
recording and playback Dolby circuits extend this
Dual Monitoring feature to cover Dolby recording
as well.
For private headphone listening, connect stereo
headphones and set Monitor Switch to TAPE
position.
* Set Monitor Switch to TAPE position for play-
back through a speaker system.
* For monitoring during recording, the use of
headphones is recommended.
SOUND MIXING
Independent line and microphone recording level
controls and input jacks enable signals from micro-
phones and from line sources to be blended and
recorded simultaneously on the tape.
Connect microphones to Microphone Jacks and
connect desired source to the Line Input Jacks.
Follow recording procedure, adjusting both Line and
Microphone Input Level Controls.
TIMER: RECORDING — — —— — ———— — —— ——
By using an external timer together with Akai Re-
mote Control Unit RC-17 or RC-18, absentee re-
cording can be accomplished with this machine.
Connect Remote Control Unit to Remote Control
Jack and properly load a tape. Plug in AC Cord
through the external timer. Adjust input level follow-
ing recording procedure and with the Power Switch
turned ON and the Remote Control Unit REC and
FWD Play Keys locked into recording mode posi-
tions, set timer, following manufacturers instructions.
If timer is set to coincide with source timing, the
GXC-760D will automatically begin recording ac-
cording to setting.
* This machine features Automatic Stop which
will be effected at the end of the tape.
HEAD CLEANING HH
It is important for the heads and the head block
area to be kept clean at all times as dust adhering
to these parts deteriorates sound quality.
1. Turn off Power Switch.
2. Remove cassette from receptacle.
3. Lift off cassette lid (with tape view window) by
lifting upward.
4. Clean recording/playback and erase heads with a
cotton swab stick dipped in Akai Cleaning Fluid
